Title: Fixed side flange
Inventor: KAWAKAMI HIROSHI
IPC: B24B45/00
Filed: 1994-10-07
Abstract: PURPOSE: To provide a fixed side flange having low return torque by which fastening of a fastening side flange becomes weak and a grinding wheel does not fall off even in a condition where a switch is turned off without performing grinding work. CONSTITUTION: A steel plate 22 is arranged so as to contact with a part 13 to transmit rotation, and torque is received by projecting parts 19 arranged on a fixed side flange body 14 and corresponding parts 20, and they are calked by deforming parts 21, and are formed as a slipping out stopper. Spring corresponding parts 23 and restraining parts 24 exist in the steel plate 22, and the restraining parts 24 restrain so as to reduce a play with a meshing part of a grinding wheel spindle 6 with a flange. Since the grinding wheel spindle 6 of a two-dot chain line is restrained by bringing it near to the fastening side, when a grinding wheel tries to loosen after a switch is turned off, restraint by a spring acts, and looseness can be prevented. When spring force is set in a proper value, the grinding wheel can be easily removed in small return torque.

Title: Spontaneous light-emitting indicator type instrument
Inventor: MIYAZAKI KAZUHIKO
IPC: G01D11/28
Filed: 1994-10-07
Abstract: PURPOSE: To efficiently guide light emitted from a spontaneous light-emitting element outside an indicator thereby to increase the luminance of the indicator by forming the upper end width and the lower end width of a semitransparent part equal to each other and setting a side face at right angles to a housing. CONSTITUTION: Each LED 13 within a spontaneous light-emitting indicator 1 which is supplied electricity via a flexible printed circuit board 12 is lit and the light emitted from the LED enters a transparent synthetic resin 16. At this time, is light radiated in a lateral direction is reflected at a side face 11b of a groove part 11B, most of which enters a refraction lens 14 and scatters in a longitudinal direction of the indicator 1. The scattering light enters a semitransparent part 15a of a cover 15 and is radiated outside the indicator through an upper end face 15d. Since the width of each of the upper and lower end faces 15d and 15c is the same L1 as the width of an opening of the groove part 11B, the light passing through the opening of the groove part 11B does not scatter in a widthwise direction at the semitransparent part 15a, so that the luminance is not weakened.  Although a part of the light is reflected at a side face 15b, the side face 15b is perpendicular to a housing and therefore an angle of incidence of the reflecting light becomes smaller than a critical angle at the time of total reflection at the end face 15d, whereby the light is radiated outside. Accordingaly, the light emitted from the LED 13 can be efficiently radiated from the end face 15d.

Title: Method for assembling clad steel blank material
Inventor: KONUMA YUKIO
IPC: B23K20/04
Filed: 1990-09-15
Abstract: PURPOSE:To surely and easily separate the part which eliminates the need for jointing after press-contacting work and to stably manufacture without a personal difference by composing the carbon steel foil to use together with the titanium foil as the stripping material of the steel carbon content volume is higher than the dummy material. CONSTITUTION:For example, when four sides of the laminating surface of the clad steel blank material assembled by using the dummy material of carbon steel is welded, heated and rolled, and the laminated material of the base steel material and the Cu system metal is press contacted, the forming of the titanium carbide structure layer is advanced faster between the carbon steel foil with higher carbon content than the dummy material and the titanium foil during this treatment. Therefore, the sufficiently weak layer is interposed at the boundary surface of the carbon steel foil with the titanium foil having priority over the boundary surface between the dummy material and the titanium foil, so applying the force to strip the dummy material after cutting the clad material to the prescribed dimension, the titanium carbide weak layer formed at the boundary surface between the carbon steel foil and the titanium foil is easily destroyed, and the dummy material is easily stripped in the state with the titanium foil stuck as it is.
